TREATING-CHAMBER FOR STERILIZING-MAGHINES.

Specification of Letters Patent.

Patented June it, T915.

Application filed November 22, 1910. Serial No. 593,634.

To all whom it may concern:

Be it known that 1, WILLIAM B. FENN, a citizen of the United States, residing at Golumbus, inthe county of Franklin and State of it shown in the accompanying drawing and set forth in the following description, the features ofnovelty being pointed out in the claim appended to the description.

In the said drawing- Figure 1 is a horizontal section on the line w-m Fig. 2 and Fig. 2 is generally a vertical section of the device on the line 'yg Fig. 1. Fig. 3 is a detail partly in section showing the treating head depressed.

In the views '3 designates a cylindrical chamber having on its side at its lower portion an opening 3 sufiiciently large to admit the can or container of the products to 'be treated. Suitably hinged to the-exterior of the chamber as at 4.- is a door 5 adapted to close the opening 3- and to insure tightness of the closure there can be provided a packing 6. The inner side of the -door 5 at its lower portion has projecting from it a shelf or support 7 adapted to receive the aforesaid can or container, an example of whichis shown and designated 8.

Inthe upper portion of the chamber 3 is a piston 9 and below this piston ahead 10 the two being connected but separated by a space 11. The head 10 is ,furnished with a nozzle 12 preferablyperforated to discharge sterilizing material laterally. The sterilizing head and nozzle can be of any suitable construction, such sterilizing head not in" its details constituting a part of the present invention. The chamber 3 has connected with it a pipe 13 for admitting fluid pressure to depress the piston and treating head. When the sterilizing head' s properly depressed it closes the upper end of the can whichis left open and the nozzle penetrates the material in the can as shown in :Fig. 3.

14 designates a pipe connected with the chamber to admit the treating material. The discharge end of this pipe is'located so that when the sterilizing head is depressed the treating agent is admitted to the space 11 between the piston and the head from which the sterilizing agent passes through the duct 10 in the head to the treating nozzle.

15 designates a pipe connected with the lower portion of the chamber to admit pres- ,sure around the exterior of the can and prevent it from bursting if the pressure of the sterilizing agent be greater than can be withstood by the can. I

Where the sterilizing chambers are arranged in a moving circular series it is important that some means he provided for holding the doors closed. The means shown for this purpose consists of a stationary rail 16 having a beveled end 16 and a roller 17 mounted on a bearing which can be the shank of a bolt 18 secured on ears 19 on the outer side of the door 5. When the moving chamber containing the can approaching the rail contacts with the beveledv end 16 the door is given a closing movement and is finally tightly closed by the inner side of the rail. I

The forms of the parts can be varied without departing from the gist of the invention.

What I claim is:

1. In a sterilizing machine, the combination of a chamber having an opening for the insertion of a vessel, and means in the chamber for applying a sterilizing agent to a vessel in said chamber, a door for said opening, and a shelf on said door-to receive the vessel.

2. In a sterilizing machine, the combination. of a chamber, having an opening in its upright side for the insertion of a vessel,

a vessel in said chamber, a door for said 10 opening and means consisting of a rail to- Ward which the doormay be moved to close the same, substantially as-described.

WILLIAM B. FENN.
